SHOCK-ABSORBER.

Application filed March 6, 1913.

T00 whom it may concern:

Be itknown that I, WILLARD T. SEARS, a citizen of the United States,residing at Hartford, in the county of Hartford and- State ofConnecticut, have invented certain new and useful Improvements inShock-Absorbers, of which the following is a specification. Y

. This invention relates to so-called shockabsorbers for vehicles one ofthe primary objects of the invention being to provide an article of thischaracter which is simple in construction and certain and positive inaction and by which relativemotion of certain members of the vehicle,will be effectually resisted, and thereby prevent excessive andprolonged vibration of one of such members, such as the body.

In the drawings accompanying and forming part of the presentspecification, I have shown two of the several forms of embodiment ofthe invention, which to enable those skilled in the art to practice thesame, will be set forth fully in the following description. I do notlimit myself to this disclosure;.I can depart therefrom in severalrespects within the scope of the invention 'defined by the claimsfollowing said description. I

Referring to said drawings: Figure 1 is a rear elevation of a vehicleprovided with shock-absorbing means involving my invention, saidshock-absorbing means, however,

being merely shown diagrammatically or all the parts thereof notappearing. Fig. 2 is asectional view of the shock-absorber, and

portions of the vehicle. Fig. 3 is a. detail view in elevation of aturbine member.. Fig.

4 is a sectional elevation of another form of the device, the operatingmeans for the gyro static member being omitted as is the case withFig. 1. v 3

Like characters refer to like parts through.

out the several views which are on different scales.

My shock-absorber is capable of advantageous use in connection withvehicles of various kinds but is of especial utility when incor oratedin those accustomed to travel over ighways or common roads as they areknown in contradistinction to railroads.

' While it can be embodied in a railroad car there is generally nonecessity therefor-as ordinarily the rails are sufiiciently, smooth toinsure easy riding. v I

The invention comprises as to one of its Specification of LettersPatent.

broader aspects, a gyrostat for resisting rela-i tlve motlon of any twodesired elements or 1 members of the vehicle and usually, but notessentially, these two members will be the running gear and the body ofthe vehicle the gyrostat being preferably interposed between saidrunning gear and body to secure the desired advantage, viz., ease andcomfort to the occupants of the carand the practical elimination ofjolts and jars to the mechani-' able means may be provided for operatingthe gyrostat. I prefer, however, that the driving device be of suchcharacter that the speed of the gyrostat shall be approximatelyproportional with the speed of the car so that when thelatter is-movingslowly a corresponding motion of the gyrostat ensues .while when the caris driven fast the speed of the gyrostat will be correspondingly accelerated. I may if desired employ the Y motor which operates theQcar,to drive the gyrostat. Said motor can be of any -suitable type.

With the foregoing general observations I will now specifically refer toFigs. 1, 2

and 3. In the first of these views an automobile is illustrated in rearelevation, and comprises the body '1 and the axle 35 equipped with thecustomary wheels. f Between the v axle (constituting part of the runninggear of the car) and the body are situated one or more springs of anydesirable kind, there bein two of such illustrated and denoted by Thegyrostat shown comprises i its make-up a m'emberwhich'has both a rotarysatisfactorily as such a rotary and revoluble member being-asillustrated, integral with the sleeve .5 which projects opjipsitelytherefrom substantially centrally t sleeve is loose on the shaft 20' bywhich the efiect of the rapidly rotating Wheel is trans- 'ferred to therunning gear of the vehicle in' I ereof.

Through thelatterextends the pivot 26' which is ordi ,narily in construction likethe pin 2 already described.
